Propellantless stationkeeping for VLEO satellites


The Calypso is much lighter than competing stationkeeping options, weighing a fraction of smallsat mass.

We are building the Calypso, an electrodynamic tether-based propellant-less propulsion device that will enable Very Low Earth Orbit satellite missions.

More reliable

We’re engineering a reliable deployment mechanism so that, unlike previous tether missions, ours will get the job done.


We’re building smart software to control and predict our tether’s trajectory, continually improving mission safety.


Because it is propellantless, it will last much longer, resulting in a theoretical lifetime of up to a decade.
